Many members here, including avocet8, claim significant length gains (1”) from pumping. I’m not one of them, but I have gained noticable girth. Most of us use pumping to compliment our usual PE routines.
The “pumped” enlarged effect is temporary, but theoretically if you do it regularly for a long enough time the enlarging effect will accumulate. How long of a time? Nobody can say. Everyone reacts differently.
Read all the related posts on this site and the articles on pumping and you should get a good idea of what to expect, and how to pump safely.
Also, please use punctuation in your posts to make them more legible. Periods (.) and commas (,) are very useful symbols.
